If it's an issue with you being unsatisfied with your boyfriend's skill in bed, then you should talk to him. If you fake it, then he'll never get better, and if he gets mad when you bring it up then he has some maturing to do. If it's because of a lack on intimacy in your relationship in general, again, conversation is key. You can't expect anything to improve if you don't say you find it lacking. Then again, if you do or have done all of that and things haven't improved, then I think it's time think about moving on. That's assuming your dreams are because you're not satisfied... If that's not the case then by all means ignore all of that.

vibrators can make sex/intimacy less enjoyable because of over stimulation. don't get me wrong, they're great toys to have but using them too much can make it harder to achieve a climax without them. you need to think on why you don't have the sexual excitement with your boyfriend. is it the boring same old stuff? spice it up! is it he doesn't brush his teeth? make a suggestion. is it you? find out why you're more aroused with a vibrator.
